Since doing the 5:2 IF, I go hungry even on my NFD. I just heard about Keto mentioned in a post. I want to try it out so I don’t feel hungry again right away after I just eat or feel lethargic throughout the day.

However, I do want to keep it under the 1200 calories range. So what can I eat that would increase my GOOD fat intake, and lower my carbs ?

Anything in the cabbage family – kale, broccoli, cauliflower, etc.
Bone broth, broths in general
Butter, full fat dairy depending on who you follow.
Check some keto sites – I like Dr Jason Fung (Canadian) but lots of others out there.
Chronometer is a decent website to check breakdown of foods.

Recommend the 2ketodudes forum for info & recipes, as well as Jason Fung. The idea of keto is not calorie counting though, but keeping an eye on carbs. And it can take 6-8 weeks to get fat adapted, & until you have that metabolic change you’ll likely still feel hungry, so it’s not a quick fix…
